Perhaps the most important discoveries are those which relate to the appropriate distribution of the periods of study...Acts of revision should be spaced in gradually increasing intervals, roughly intervals of one day, two days, four days, eight days, and so on.

The forgetting curve hypothesizes the decline of memory retention in time. This curve shows how information is lost over time when there is no attempt to retain it.

From 1880 to 1885, Hermann Ebbinghaus ran a study about the memorisation of nonsense syllables, such as "WID" and "ZOF" by repeatedly testing himself after various time periods and recording the results. He plotted these results on a graph creating what is now known as the "forgetting curve".

Murre and Dros present a successful replication of Ebbinghaus’ classic forgetting curve from 1880 based on the method of savings. The forgetting curve has indeed been replicated and that it is not completely smooth but most probably shows a jump upwards starting at the 24 hour data point.

The speed of forgetting depends on a number of factors such as the difficulty of the learned material (e.g. how meaningful it is), its representation and physiological factors such as stress and sleep. Furthermore higher original learning also reduces forgetting. The rate differs little between individuals.

Spitzer tested 1939 the effects of a type of spaced repetition with over 3600 students who were learning science facts and showed that spaced repetition was effective.

Spaced practice is a feasible and cost-effective way to improve the effectiveness and efficiency of learning, and has tremendous potential to improve educational outcomes.

Memory formation becomes more effective with longer inter-stimulus intervals between training sessions because of decreasing temporal overlap between successive, short-lived learning traces.

Organizations spend hundreds of hours and hundreds of thousands of dollars installing and implementing huge servers, new Web sites and applications. They have to continue to do that, but they also have to clean up the mess of the '90s.

Companies are bought for their revenue, customer base, technology, or people. A few great companies offer all of these, but any valuable business offers one.

Everything family does is reflection on the other people.

I just hate sitting and writing - I had to do that in school. Plus, I have terrible handwriting.

I don't personally follow trends; I don't even like the idea of trends. I think it's kind of absurd that you have to change every six months, so I always try and buy things that hopefully I'll like forever, and resonate with me.

We have benefited greatly from the globalization of the economy in the last 30 years.

We learn about tithing by paying it.

Although just being employed as an actor is a big thing, I'm not sure I'd be satisfied playing the same character for 30 years; it's not why I want to do this for a living.

Cunning... is but the low mimic of wisdom.

As with the factory, so with the office: in an assembly line, the smaller the piece of work assigned to any single individual, the less skill it requires, and the less likely the possibility that doing it well will lead to doing something more interesting and better paid.

If we're not supposed to eat animals, how come they're made out of meat?

I spent as much time writing proposals in '98 and '99 as I did writing scripts.

It's always the compliments from people you love that mean so much.

Grandmas hold our tiny hands for just a little while but our hearts forever.

I think I need a psychiatrist because I do believe I am mentally disturbed in some way.

The consideration of change over the century is about loss, though I think that social change is gain rather than loss.

The more selfless service you do, the more successful you will.

I like banks because they keep my money safe, but I don't want to talk about banks 12 times a year.

It's a weird thing because I've been single at the time when I've been successful. That's good and bad. Good, because you meet lots of people, bad because your privacy is infringed, so it's harder to develop things.

We never do Valentine's dinner, because everybody, they look. On Valentine's, imagine me and David going to a restaurant! Like, everybody's going to say, 'Did they talk? Did they hold hands?' Twenty years. We've been married twenty years!

I started writing 'Brick Lane' when my children were two years and five months old. We were on holiday in the north of England when I was overtaken by a compulsion to start writing.

If I'm in the bookstore, and I see a 700-page novel, my first thought is, 'Ooh, how could you cut this down to size and make a movie out of it?'

To an ant on the ground, an airplane probably looks like an ant.

It is best to be on the safe side
